I kno ppl who leave things in the garage i wont put anything on or new the floor for the fact you never know if it will flood. i dont think it would be to bad if its up some what high. i would put anything in the basement for the fact it could flood as well.. and thats my fear with all the rain some areas get flooding has been an issue.. if you do deside to use it for storage make sure its in a good bin with a lid just incase good luck
